The Geberit Sigma Slimline Concealed Cistern is designed for modern bathrooms where space-efficient installation and a neat finish are important. With its slim 80mm depth, this concealed cistern fits discreetly within suitable pre-wall or partition wall installations, helping maintain a clean, uncluttered toilet area. Manufactured from plastic with a white finish, it combines a practical design with the established Geberit Sigma range. The cistern is intended for floor-standing back-to-wall WC pans and features front actuation. Suitable for part-height or room-height installations, it provides a discreet flushing solution for contemporary bathroom projects where a compact concealed arrangement is required.
Designed for installation in drywall or masonry walls, the Geberit Sigma cistern offers tool-free installation and maintenance. Its flush bend is fitted, and the cistern is fully insulated against condensation. The factory flush setting is 5.8/3 litres, with adjustment available for the small flush volume. The water supply connection includes an integrated angle stop valve and hand wheel, while the service-opening protection box helps protect against moisture and dirt and can be cut to length. Compatible with more than 120 Geberit Sigma flush plate finishes, it also supports installations requiring electrical connections for suitable devices. The package includes the flush bend, fastening components, protection plug, flush-volume reduction cup and fixing brackets. Images are for illustration purposes only.
